EARLIER: Two dogs and several people waited under police watch in a yard at a Dundowran home yesterday as detectives executed a raid on an alleged meth lab.

Police were seen entering the lower level of the two-storey home.

Inside, they allegedly uncovered equipment associated with the production of methylamphetamine.

A Queensland Police spokesman confirmed a search warrant was executed at the address.

He said eight people were last night assisting police with their ongoing inquiries.

No charges have been laid in relation to the raid.

The alleged discovery of the meth lab in Dundowran follows the arrest of 17 people last year in connection with a meth trafficking network on the Fraser Coast. The arrests followed a 12 month investigation by police.
